javascript - How to make code wait while calling asynchronous calls like Ajax

I am looking for something like
this

function someFunc()
            {

callAjaxfunc(); //may have multiple ajax calls in this
            function
someWait(); // some code which waits until async calls
            complete
console.log('Pass2');

}

function
            callAjaxfunc() {
 //All ajax calls called here

            console.log('Pass1');

}

What
I have
tried?

1

Jquery.when()

tried using it..it works fine. But
not the way I want. $.when will wait but the code next to
$.when() runs with out waiting. The code inside do
callback only runs after ajax
calls

2.
setTimeOut()
with a global flag

I was so confident this will
work. I tried like
following.

GlobalFlag =
            false;

function someFunc() 
 callAjaxfunc(); //may have
            multiple ajax calls in this function
 setTimeOut(waitFunc, 100); // some which
            waits until async calls complete

            console.log('Pass2');
}

function callAjaxfunc()
            {
 //All ajax calls called here
 onAjaxSuccess: function()
            {
 GlobalFlag = true;
 };
 console.log('Pass1');
            
}

function waitFunc() {
 if (!GlobalFlag)
            {
 setTimeOut(waitFunc, 100);

            }
}​

Still
not able to get wanted result. Am I doing something wrong here? This is not the
way?

Result I wanted should come like
this

Pass1
Pass2

Not
able to make any fiddle as it needs AJAX
calls

EDIT: As many
were suggesting callbacks..i know about them..but still the code next to
somewait() will get executed...I want browser to completely
stop executing code next to somewait() until the ajax
call..Also it may be a bad practice but worth to know and try if
possible...

Use
callbacks. Something like this should work based on your sample
code.

function someFunc()
            {

callAjaxfunc(function() {

            console.log('Pass2');
});

}

function
            callAjaxfunc(callback) {
 //All ajax calls called here

            onAjaxSuccess: function() {
 callback();
 };

            console.log('Pass1');
            
}

This will
print Pass1 immediately (assuming ajax request takes atleast a
few microseconds), then print Pass2 when the
onAjaxSuccess is executed.
